Abstract
In this work, experimental data and a simplified vapor-liquid equilibrium (VLE) model for the absorption of CO2 into aqueous solutions of 3-methylaminopropylamine (N-methyl-1,3-propane diamine – MAPA) and dimethyl-monoethanolamine (2-dimethylaminoethanol – DMMEA) are reported. The chemicals were selected based on kinetic, energy and environmental properties for post-combustion CO2 capture. The effect of the DMMEA/MAPA ratio and the total concentration level of amine were studied. Based on the results of preliminary semi-quantitative tests (screening) the best amine ratios were determined. Two amine concentrations were selected for the VLE study. The result of both the screening and the VLE measurements are compared to the generally used 5M (30 mass %) monoethanolamine (MEA) solution. The presented systems seem to be better performing than 5M MEA, and have significantly higher cyclic capacity combined with moderate impact on the environment.
